Contrary to popular opinion, heart attacks are not usually heralded by obvious or classic signs — such as the infamous “Hollywood” heart attack, in which a person clutches at his or her heart dramatically, doubled over with severe chest pain.

We all know the classic symptoms — pain, pressure, weakness, breaking out in a cold sweat.

But what you might not know is that 25 percent of all heart attacks occur "silently," meaning there are no clear or recognizable symptoms. Unfortunately, these silent heart attacks are frequently fatal, particularly because so many people delay or fail to seek medical treatment.

Here’s a shocking but true statistic: if you suffer coronary arrest outside of a hospital you have just a 7 percent chance of survival!

These symptoms can be so mild or vague (like fatigue), most people don’t even realize it’s heart-related (unless they are made aware). Four things in particular are the most sinister signs of a silent heart attack.

Dr. Crandall, is a Yale-trained physician, NY Times bestselling author and one of America’s leading cardiologists, has spent decades busily working to prevent, minimize, and reverse heart disease.

Over this time, Dr. Crandall has come to recognize that the heart does usually warn people of a potential heart attack minutes, days, or even weeks before the event.

However, since these warning signs are often subtle and thus ignored, Dr. Crandall has created a complimentary video presentation to help you recognize the four commonly overlooked signs you will soon suffer a heart attack — so you can seek the treatment you need before it’s too late.

Timing is the most critical factor for survival.

Statistics show a clear link between delay in treatment and disability or death — the amount of time that elapses between the first sign of symptoms and receiving care.

Here, Dr. Crandall tells the real-life story of a "widow-maker" heart attack that did not have to happen.

It's scary, but eye opening because he outlines what could have been done to actually prevent this.

Dr. Crandall, chief of the cardiac transplant program at the esteemed Palm Beach Cardiovascular Clinic in Florida, practices on the front lines of interventional, vascular, and transplant cardiology.

Years of experience have afforded him the chance to detect little known warning signs and symptoms like the four he addresses.

He has saved countless lives. Yours could be one of them!

The real value in this presentation is the number of simple strategies he outlines to help prevent heart disease. Strategies that many doctors just don’t take the time to discuss with patients until they’re already showing obvious symptoms of cardiovascular stress.
